Help with this update statement..

Hi everyone,
I am trying to update a column in a table .I need to update that column
with a function that takes patient_nbr and type_x column values as a parameter.
That table has almost "300,000" records. It is taking long time to complete
almost 60 min to 90 min.
Is it usual to take that much time to update that many records?
I dont know why it is taking this much time.Please help with this update statement.
select get_partner_id(SUBSTR(patient_nbr,1,9),type_x) partner_id from test_load;
(it is just taking 20 - 30 sec)
I am sure that it is not the problem with my function.
I tried the following update and merge statements .Please correct me if i am wrong
in the syntax and give me some suggestions how can i make the update statement fast.
update test_load set partner_id = get_partner_id(SUBSTR(patient_nbr,1,9),type_x);
merge into test_load a
using (select patient_nbr,type_x from test_load) b
on (a.patient_nbr = b.patient_nbr)
when matched
then
update
set a.partner_id = get_partner_id(SUBSTR(b.patient_nbr,1,9),b.type_x);
there is a index on patient_nbr column
and the statistics are gathered on this table.

Hi Justin,
As requested here are the explain plans for my update statements.Please correct if i am doing anything wrong.
update test_load set partner_id = get_partner_id(SUBSTR(patient_nbr,1,9),type_x);

update holds set area = (select newarea from stagesteps)
where holds.stage= stagesteps.stagename and holds.step = stagesteps.STEPNAME and holds.area is not null
When I do this, it says stagesteps.stepame is an invalid name..
Any helps on this highly appreciated.. btw Advance thanx for your help.

update holds h
   set area = (select ss.newarea
                 from stagesteps ss
                where ss.stagename = h.stage

where area is not null
   and exists (select null
                 from ss.newarea
                 from stagesteps ss
                where ss.stagename = h.stage
                  and ss.stepname = h.step);You can leave off the EXISTS clause if there will be a guaranteed matching row in stagesteps for each row in holds, or if you don't care if area is set to null if there is no match.

What is wrong with this update statement

Hi all,
I am trying to create a simple update program that allows user to enter table name, key fields and one field to update and its value.

Can you please help with this select statement.

The following code has a result, I need to modify the select somehow which only gives me the rows which are common between all PLSTS.
Any suggestions?
Thank you
SELECT DISTINCT P.PLST, P.MENU, I,PNL, P.ACCESS
FROM AUTHITEM P, I.MENUITEM
WHERE P.MENU = I.MENU
AND P.PNL = I.PNL
AND P.MENU IN ('MSN, CPP')
AND P.ACESS >= 8
GROUP BY P.PLST, PMENU, I.PNL, P.ACCESS
HAVING COUNT (*) >=2
ORDER BY 2,3,4,1
This is the result with having count > = 1, and if I add having count > =1 I get the following result
PLST     MENU     PNL     ACCESS
C001     MSN     LNAME     14
C002     MSN     LNAME     14

I need this result

C001     MSN     FNAME     14
C002     MSN     FNAME     14

why bother with DISTINCT ?
have a look at the results of :
SELECT P.PLST, P.MENU, I.PNL, P.ACCESS , COUNT(*) ZCOUNT
FROM AUTHITEM P, I.MENUITEM
WHERE P.MENU    = I.MENU
   AND P.PNL     = I.PNL
   AND P.MENU IN ('MSN, CPP')
   AND P.ACCESS >= 8
GROUP BY P.PLST, P.PMENU, I.PNL, P.ACCESS
ORDER BY 2,3,4,1
;and then apply HAVING COUNT(*) >= ...

I need help with this while() statement please!

Need help with this CASE statement

Hi everyone,
I would like to create a CASE that references another view and uses fields in that view to create a new field in a new view.
The fields I am working with are called LEVEL_CD and AVAILABLE_AMT.
In this case I would like to create a field called AVAILABLE_AMT (in my new view) that inserts the AVAILABLE_AMT from the old view into the new field only if the LEVEL_CD = 1. If the LEVEL_CD is anything else but 1 I would like to insert a 0 into my new
AVAILABLE AMOUNT field.
This is what I have so far and it doesn't seem to work:
CASE WHEN old_view.LEVEL_CD = 1 THEN old_view.AVAILABLE_AMT
WHEN old_view.LEVEL_CD <> 1 THEN 0 END AS AVAILABLE_AMT
This just gives me zeroes in every record. Can anybody spot what I am doing wrong?
Thanks!

SELECT <columns>,CASE WHEN old_view.LEVEL_CD
=
1
THEN old_view.AVAILABLE_AMT
ELSE 0 END AS AVAILABLE_AMTFROM old_view.PK JOIN new_view.PK WHERE....PS.PK -Primary Key

Help with a update,select statement

Hi all please can you help me with a update statement i am struggling with.
I have 2 tables
Holiday and data
In the Holiday table i have columns for
Machine_ID NUMBER,
date_from DATE,
date_to DATE,
ID NUMBER
Machine column represents a type of machine, the two dates represent the start and end date of a holiday and ID represents the ID of the machines that the holiday effects (as you can have many machines that are the same, so the ID unique field to seperate them.
i.e.
996     25-DEC-08 00:00:00     27-DEC-08 00:00:00     91
996     25-DEC-08 00:00:00     27-DEC-08 00:00:00     92
100     28-DEC-08 00:00:00     29-DEC-08 00:00:00     1
100     28-DEC-08 00:00:00     29-DEC-08 00:00:00     2
In the data table i have the following columns:
DATE DATE
Machine NUMBER
SHIFT1S DATE
SHIFT1F DATE
SHIFT2S DATE
SHIFT2F DATE
CALS DATE
CALF DATE
CAP NUMBER
CALCAP NUMBER
total_hrs_up NUMBER
In here i have data for every date in the calendar. The machines are cross references with the machine in holidays table.
I run two shifts so have shift 1 start, finish. shift 2 start, finish. These are dates with times, so shift1s could be 01-01-08 09:00:00 shift1f could be 01-01-08 17:00:00.
shift2S could be 01-01-08 21:00:00 shift2f could be 01-01-08 23:59:00.
so that machine would be up between them hours of the day.
Other columns include
CALS, ,CALF = calendar start, finish, - This needs to be populated from the holiday table. currently null. So if the date is the 26 DEC and the machine is the same as what is in the holiday table then these two columns should be populated with them data
CAP is the total number of these machines i have available.
CALCAP is the no of machines the holiday affects -currently null
total_hrs_up is the number of hours this machine is up and running -currently null.
So what i need to do is populate the cals, calf calcap, total_hrs_up columns.
total_hrs_up is the important one, this needs to work out based on the two shift patterns the number of hours that the machine is available and then take off the holiday hours to give a final value.
so current data example in data is
date machine shifts shiftf shift2s shift2f cals, calf, cap, calcap, total_hrs
16-JUL-08     100 09:00:00     17:00:00     12:00:00     00:00:00               '','','',1     ,''
16-JUL-08     105 09:00:00     17:00:00     12:00:00     00:00:00               '','','',1     ,''
16-JUL-08     107 09:00:00     17:00:00     12:00:00     00:00:00               '','','',1     ,''
id like to see based on the holiday table if there is a holiday then this data is updated as such and a total_hrs machine is available populated on that date.
Any help is very much appreciated!
Thanks

Hi,
The following query does what you requested.
It makes the following assumptions:
(a) in data, shift1start <= shift1finish
(b) in holiday, hol_start <= hol_finish
(b) in data, the combination (machine, shift1start) is unique
(c) in holiday, hol_start <= hol_finish
(d) in holiday, rows for the same machine and id never have overlapping dates (including times). For example:
INSERT INTO holiday (machine, id, date_from, date_to)
VALUES (200, 1, '26-DEC-08 07:00:00', '26-DEC-08 09:59:59');
INSERT INTO holiday (machine, id, date_from, date_to)
VALUES (200, 1, '26-DEC-08 09:00:00', '26-DEC-08 09:59:59');will cause a probem. Multiple rows for the same machine and day are okay, however, if the times do not overlap, like the following:
INSERT INTO holiday (machine, id, date_from, date_to)
VALUES (200, 1, '26-DEC-08 07:00:00', '26-DEC-08 08:59:59');
INSERT INTO holiday (machine, id, date_from, date_to)
VALUES (200, 1, '26-DEC-08 09:00:00', '26-DEC-08 09:59:59');Here's the UPDATE statement:
UPDATE     data     m

     ,     MAX (date_to)
     ,     (     MAX (shift1finish - shift1start)     -- Total from data
          -     ( NVL     ( SUM     ( LEAST (date_to, shift1finish)

If the thief enabled activation lock on the device, then there is nothing that can be done. Only the password for the Apple ID that it is locked with can disable activation lock.

I cannot download updates to Photoshop Elements 9. I get an error message that my serial number is not recognized or eligible. Can you help with this?

Hi,
Which operating system are you running on?
What updates are you trying to download?
The last update was 9.0.3 - check by loading the editor and going to Help -> About Photoshop Elements
The last supported Camera raw is ACR 6.5 - check by loading the editor and going to Help -> About Plug-ins -> Camera Raw
Do you have a reason to update?
Brian

Apps downloaded with an Apple ID are forever tied to that Apple ID and will always require it to update.
The only way around this is to delete the apps that require the other Apple ID and download them again with yours.
Or simply log out of iTunes & App stores then log in with updated AppleID.

I recently updated my computer to 10.6 and now I can't get my printer MX340 (canon ) to work. I have installed the new drivers both from Canon's website and from an earlier post directly from apples website. I would surely appreciate some help with this.

Re: Is Iphoto gone ? i want it back!

Go to the App Store and check out the Purchases List. If iPhoto is there then it will be v9.6.1
If it is there, then drag your existing iPhoto app (not the library, just the app) to the trash
Install the App from the App Store.
Sometimes iPhoto is not visible on the Purchases List. it may be hidden. See this article for details on how to unhide it.

One question often asked: Will I lose my Photos if I reinstall?
iPhoto the application and the iPhoto Library are two different parts of the iPhoto programme. So, reinstalling the app should not affect the Library. BUT you should always have a back up before doing this kind of work. Always.

everything should be on your computer.
If you do as you should and make sure that everything is on your computer, then you should lose nothing.

Help with this update statement..
